- 250mls of 91% isopropyl alcohol
- 125mls of aloe vera gel (natural or store-bought)
- 15 drops of tea tree oil (or another antibacterial essential oil)
1. Pour the alcohol into a medium beaker.
2. Measure and pour the aloe vera gel. Alcohol can be hard on your skin, so using aloe is a good way to counteract that effect and keep your hands smooth. If you want to keep things natural, you can use aloe vera gel straight from the plant without worrying about it going bad—the alcohol will act as a preservative. However, you will need to keep in mind that natural aloe gel is thicker than its store-bought counterpart and will thus affect the final product differently—it will make your hand sanitizer more sticky, which means you’ll need to rub your hands more times for it to fully absorb.
3. Add the essential oil. Tea tree oil is naturally antibacterial, so it makes sense to use it here. But if you’re not a fan of its smell, you can use another type of essential oil, like lavender, lemongrass, or eucalyptus.
4. Whisk. To fully mix all ingredients, stirring won’t be enough. Get a whisk and beat that hand sanitizer into an homogeneous gel.

5. Sanitize your spray bottles and pour in your hand sanitizer. Spray some of your leftover alcohol into your bottles and let them sit until the alcohol has evaporated. Pour in your sanitizer.
